DESCRIPTION

vgextend allows you to add one or more initialized physical volumes (see pvcreate?(8)) to an existing volume group to extend it in size. Moreover, it allows you to re-add a physical volume that has gone missing previously, due to a transient device failure, without re-initialising it. Use vgextend --restoremissing to that effect.

If PhysicalDevicePath was not previously configured for LVM with pvcreate?(8), the device will be initialized with the same default values used with pvcreate?(8). If non-default pvcreate?(8) values are desired, they may be given on the commandline with the same options as pvcreate?(8). See PHYSICAL DEVICE OPTIONS for available options. Note that the restore-related options such as --restorefile, --uuid and --physicalvolumesize are not available. If a restore operation is needed, use pvcreate?(8) and vgcfgrestore?(8).
